Science Data Bank (ScienceDB) is a public, general-purpose repository that supports open science by helping researchers and organizations publish, preserve, share, and access research data. Its services are intended for individual researchers, research teams, academic journals, publishers, institutions, and universities. ScienceDB provides a guided publishing process: submitters describe their datasets and upload files, after which professional data curation helps assess data quality and credibility.

For published datasets, the platform assigns a DOI and CSTR, offers multiple sharing options, and uses the SciChain anti-tampering mechanism. It also provides citation information and data-use metrics to help users track the reach and use of their data. ScienceDB features searchable collections, including latest, popular, and most-cited datasets, alongside data papers, rankings, and specialized data communities.

Additional offerings include customized services for journals, developer tools such as an Open API, OAI-PMH, and widgets, plus guidance on data policies and preferred file formats. The platform is maintained by the Computer Network Information Center of the Chinese Academy of Sciences
